Welcome back.
00:00:01.98\00:00:02.95
We've been talking
with Dr. Neil Nedley.
00:00:02.96\00:00:03.93
We've been
talking about how to avoid
00:00:03.94\00:00:06.14
making big mistakes
concerning your health.
00:00:06.15\00:00:08.70
Dr. Neil, I just
want to clarify something.
00:00:08.71\00:00:10.47
You know, we were talking about
00:00:10.48\00:00:11.49
sexually transmitted diseases
00:00:11.50\00:00:13.40
and you've talked about,
00:00:13.41\00:00:14.78
you know, females that have
had only one sexual partner,
00:00:14.79\00:00:19.89
had a 20
percent chance of having
00:00:19.90\00:00:21.76
a sexually transmitted disease.
00:00:21.77\00:00:23.40
But then you said something
00:00:23.41\00:00:24.38
about two or more
partners and clarify for us.
00:00:24.39\00:00:28.32
Yeah, this was a study done
00:00:28.33\00:00:29.87
by the Center of Disease
Control, Dr. Sara Forhan.
00:00:29.88\00:00:33.46
And it should among those girls
00:00:33.47\00:00:35.48
who had sexually
transmitted disease
00:00:35.49\00:00:37.09
is 15 percent of
them currently had
00:00:37.10\00:00:39.21
more than one
sexually transmitted disease.
00:00:39.22\00:00:42.23
And among the
girls aged 14 to 19,
00:00:42.24\00:00:45.06
who would ever have sex,
00:00:45.07\00:00:46.64
40 percent of them
00:00:48.27\00:00:50.35
had at least one sexually
transmitted disease. Wow!
00:00:50.36\00:00:53.19
So that means it's,
00:00:53.20\00:00:54.45
you know, almost
a one in two chance.
00:00:54.46\00:00:57.35
If you're going to
choose to start having sex
00:00:57.36\00:00:59.70
between ages 14 and 19
00:00:59.71\00:01:01.48
then you're gonna end up
00:01:01.49\00:01:02.46
with a sexually transmitted
disease fairly quickly.
00:01:02.47\00:01:04.89
Which could lead to infertility,
00:01:04.90\00:01:06.47
it could lead to your
own personal discomfort,
00:01:06.48\00:01:08.68
or worse death. Exactly.!
00:01:08.69\00:01:10.95
Well, let's go
to some good news.
00:01:10.96\00:01:13.33
You wanted to tell us about,
00:01:13.34\00:01:14.99
you know, how to
avoid the double whammy
00:01:15.00\00:01:16.72
of frontal lobe hits
with loud music and alcohol
00:01:16.73\00:01:19.28
and then losing all
your money in casinos,
00:01:19.29\00:01:20.69
but what about some good news.
00:01:20.70\00:01:22.85
You have something to
tell us about a natural high
00:01:22.86\00:01:24.61
that you can get,
that's a positive study.
00:01:24.62\00:01:28.65
Yeah, we actually
need to be choosing
00:01:28.66\00:01:30.34
natural methods
of getting our highs.
00:01:30.35\00:01:33.69
You know, when we use a
drug like a nicotine or cocaine,
00:01:33.70\00:01:36.07
there's a
dopamine surge but then,
00:01:36.08\00:01:39.17
and of course
that's why people do it.
00:01:39.18\00:01:40.62
It makes them feel great,
00:01:40.63\00:01:41.94
actually higher then
they really should be feeling.
00:01:41.95\00:01:45.62
But then afterwards
there is a depravation period.
00:01:45.63\00:01:48.18
And the more they do it,
00:01:48.19\00:01:49.22
the more that
depravation occurs.
00:01:49.23\00:01:51.89
And this study that's
being demonstrated on the screen
00:01:51.90\00:01:55.45
shows one of the ways
of getting a Natural High
00:01:55.46\00:01:59.03
is when mothers see
their own infant faces.
00:01:59.04\00:02:03.50
And what happen is
key areas of the brain
00:02:03.51\00:02:05.90
associated with reward
00:02:05.91\00:02:07.59
actually lid up
during the brain scans.
00:02:07.60\00:02:10.19
This is when they smile
00:02:10.20\00:02:11.17
or when they were
changing their diaper?
00:02:11.18\00:02:12.73
Well this was particularly
when the baby was smiling
00:02:12.74\00:02:15.27
or when the baby was neutral.
00:02:15.28\00:02:16.85
These areas stimulated
by side of their own babies
00:02:18.07\00:02:20.79
were involved in thinking,
00:02:20.80\00:02:22.94
movement, behavior and emotion.
00:02:22.95\00:02:25.86
And these are the same areas
00:02:25.87\00:02:27.47
that are activated
in other experiments
00:02:27.48\00:02:30.41
by utilizing drugs.
00:02:30.42\00:02:32.82
And so the studies investigator
00:02:32.83\00:02:34.96
Dr. Strathearn mentioned,
00:02:34.97\00:02:37.34
she is from the Human
Neuroimaging Laboratory,
00:02:37.35\00:02:39.82
in Baylor College
of Medicine at Houston.
00:02:39.83\00:02:42.78
She said maybe that seeing
your own baby smiling face
00:02:42.79\00:02:47.45
is like a Natural High.
00:02:47.46\00:02:50.37
Well that sounds good
news and of course you know,
00:02:50.38\00:02:53.27
my wife stays
with the kids all day.
00:02:53.28\00:02:54.92
So she is able to get
00:02:54.93\00:02:57.66
a whole bunch of Natural Highs.
00:02:57.67\00:02:59.10
I certainly
know when I come home
00:02:59.11\00:03:00.40
I look at the kids and I go,
00:03:00.41\00:03:02.07
nothing likes to feel
better when your kids coming
00:03:02.08\00:03:04.00
over to give you a hug
00:03:04.01\00:03:05.60
and then
spending time with them.
00:03:05.61\00:03:07.49
And now this, you know,
00:03:07.50\00:03:09.23
I think some
moms sometimes think,
00:03:09.24\00:03:10.64
oh I'll be down and out,
00:03:10.65\00:03:11.93
but this is a great
thing for the brain.
00:03:11.94\00:03:14.74
It's a great thing for the brain
00:03:14.75\00:03:15.82
and the nice thing
about it is you don't get
00:03:15.83\00:03:17.58
the depravation
period afterwards.
00:03:17.59\00:03:19.46
In other words the
more your baby smiles
00:03:19.47\00:03:21.65
and the more you with your baby,
00:03:21.66\00:03:23.54
unlike using a drug
where in between times
00:03:23.55\00:03:26.28
you get this big
depravation periods
00:03:26.29\00:03:28.64
where there is no joy in life
00:03:28.65\00:03:30.74
even if you're
looking at a smiling baby
00:03:30.75\00:03:32.82
or beautiful sunset,
00:03:32.83\00:03:34.51
because the neurochemistry
has been altered adversely
00:03:34.52\00:03:37.45
from the use of these drugs,
00:03:37.46\00:03:39.14
this isn't the case
with a smiling baby.
00:03:39.15\00:03:41.17
In other words, two years later
00:03:41.18\00:03:44.30
getting that Natural
High from that smiling baby
00:03:44.31\00:03:46.89
will be just as high experience
00:03:46.90\00:03:49.09
as it was beforehand.
00:03:49.10\00:03:50.83
So what about
watching DVDs of your kids,
00:03:50.84\00:03:52.89
Do you think that
do the same thing,
00:03:52.90\00:03:54.66
watching them smiling?
00:03:54.67\00:03:55.67
Well actually the
study took a look at pictures
00:03:55.68\00:03:58.71
and when the mother was
separated from their baby,
00:03:58.72\00:04:02.61
and they saw a picture
of their own baby smiling,
00:04:02.62\00:04:05.94
it still lid up in the brain.
00:04:05.95\00:04:07.93
And so there are
advantages even at looking
00:04:07.94\00:04:10.47
at your babies
pictures at certain times.
00:04:10.48\00:04:13.27
I can hear the
photographers out there saying,
00:04:13.28\00:04:14.89
I got to use
that study in my work.
00:04:14.90\00:04:16.51
More Time Outdoors!
00:04:18.49\00:04:20.03
By the way that
study was published
00:04:20.04\00:04:21.72
in the journal
Pediatrics in July of 2008.
00:04:21.73\00:04:25.09
July 2008! More Time Outdoors!
00:04:25.10\00:04:28.26
Yes, this is a
very interesting study
00:04:28.27\00:04:30.56
showing that parents
now have another reason
00:04:30.57\00:04:34.11
to shoo their
kids outdoors to play,
00:04:34.12\00:04:36.83
along with making sure
00:04:36.84\00:04:37.81
they get enough
fresh air and exercise.
00:04:37.82\00:04:40.02
This was a study done
by Australian researchers.
00:04:40.03\00:04:43.38
And they found that children
00:04:43.39\00:04:44.38
who spend the most time outdoors
00:04:44.39\00:04:46.39
were the least likely
to suffer from Myopia.
00:04:46.40\00:04:49.75
Nearsightedness!
Which is...right,
00:04:49.76\00:04:51.17
nearsightedness
or shortsightedness.
00:04:51.18\00:04:53.59
Our evidence
suggests that the key factor
00:04:53.60\00:04:55.42
is being outdoors
and does not matter
00:04:55.43\00:04:58.13
if that time is
spent in having a picnic
00:04:58.14\00:05:00.52
or playing a sport
00:05:00.53\00:05:02.02
or whatever your
child is doing outdoors.
00:05:02.03\00:05:04.94
It actually protects your eyes
00:05:04.95\00:05:06.81
from growing excessively,
00:05:06.82\00:05:08.87
which is the
major cause of Myopia.
00:05:08.88\00:05:11.28
I want to know how that works.
00:05:11.29\00:05:12.36
Was that because you have
to change your full vision?
00:05:12.37\00:05:14.63
You're looking the
things three dimensional,
00:05:14.64\00:05:16.21
things far away, things near.
00:05:16.22\00:05:17.58
They're not sure how it works.
00:05:17.59\00:05:19.13
You know, there is
some postulation about it
00:05:19.14\00:05:21.88
and that postulation is that,
00:05:21.89\00:05:24.87
you know, your
pupils constrict more
00:05:24.88\00:05:26.98
when it's outdoor light
00:05:26.99\00:05:28.29
and so there isn't the
need maybe felt for the eye
00:05:29.57\00:05:34.67
to grow excessively.
00:05:34.68\00:05:36.63
But we do know
that nearsightedness
00:05:36.64\00:05:39.63
is a major
problem in our society
00:05:39.64\00:05:41.63
and it didn't used to be.
00:05:41.64\00:05:42.97
Back in 1900,
the amount of people
00:05:42.98\00:05:44.89
they need to glasses to see far,
00:05:44.90\00:05:47.28
at the ages of 15
and 25 were negligible.
00:05:47.29\00:05:50.00
I mean small percentages.
00:05:50.01\00:05:52.54
And now it's the
majority of kids,
00:05:52.55\00:05:55.46
you know, between
the ages of 15 and 25.
00:05:55.47\00:05:57.71
We're gonna need,
they have corrective lenses
00:05:57.72\00:05:59.95
in order to be able to see far
00:05:59.96\00:06:01.25
or wear contact lenses
or get the Lasik Surgery.
00:06:01.26\00:06:04.47
And there is
actually more than one reason
00:06:04.48\00:06:06.07
it's not just their lack
of exposure outdoor light.
00:06:06.08\00:06:08.88
In order words being
indoors all day in school
00:06:08.89\00:06:11.62
and those types of things,
00:06:11.63\00:06:12.87
but also when they have
light exposure at night.
00:06:12.88\00:06:17.02
Nightlights, for
instance have been shown
00:06:17.03\00:06:19.05
to increase the
risk of Myopia in kids.
00:06:19.06\00:06:22.45
And so it's better for them
00:06:22.46\00:06:23.43
to sleep in the dark environment
00:06:23.44\00:06:25.03
or to have very,
very low lightning,
00:06:25.04\00:06:27.72
like moonlights okay.
00:06:27.73\00:06:29.33
But if it's anything
greater than moonlight
00:06:29.34\00:06:32.82
it's going to
decrease their melatonin levels
00:06:32.83\00:06:35.04
and that maybe associated
00:06:35.05\00:06:36.70
with that eye
growing excessively
00:06:36.71\00:06:38.83
in Myopia development.
00:06:38.84\00:06:40.56
I know how to
get the kids outside?
00:06:40.57\00:06:42.62
You buy them a little kitten
00:06:42.63\00:06:44.83
and you have the kids
stay outside. There you go.
00:06:44.84\00:06:47.33
Just get one,
and they are outside.
00:06:47.34\00:06:49.84
As soon as they get up
00:06:49.85\00:06:50.89
to see how the kitten is doing,
00:06:50.90\00:06:52.13
how the little kitties are doing
00:06:52.14\00:06:53.90
and they don't want to come in.
00:06:53.91\00:06:55.12
So if you want to try
and get your kids outside,
00:06:55.13\00:06:56.87
besides from
locking them outside,
00:06:56.88\00:06:58.26
get them small animal.
00:06:58.27\00:07:00.28
That study was from where?
00:07:00.29\00:07:02.33
That study was from the journal,
00:07:02.34\00:07:03.78
Ophthalmology in August of 2008.
00:07:03.79\00:07:07.27
Large waist, as
they related to strokes.
00:07:07.28\00:07:11.44
In other words, I think
you mean midline the waist.
00:07:11.45\00:07:14.81
Yes, and that has to do
00:07:14.82\00:07:17.74
with actual waist
to hip measurements.
00:07:17.75\00:07:21.14
You know, we used
to measure obesity
00:07:21.15\00:07:24.18
by stepping on a scale,
00:07:24.19\00:07:25.81
you know, if you're up
00:07:25.82\00:07:26.79
too many pounds now that was it.
00:07:26.80\00:07:28.95
But now we know the
waist to hip ratio is even
00:07:28.96\00:07:32.30
more important than
how many pounds you weigh.
00:07:32.31\00:07:34.88
And a large waist circumference
00:07:34.89\00:07:36.43
particularly in
relationship to the hips
00:07:36.44\00:07:39.87
you have a significantly
greater risk of stroke.
00:07:39.88\00:07:43.18
The waist to hip
ratio is greater than 0.97.
00:07:43.19\00:07:46.89
You are significantly
increase risk of stroke
00:07:46.90\00:07:50.17
and that's if you are man,
00:07:50.18\00:07:52.14
and if it's greater than 0.84
00:07:52.15\00:07:54.88
you are significantly
increased risk of stroke
00:07:54.89\00:07:58.29
if you're a female.
00:07:58.30\00:08:00.33
And it turned out to
be 7.69 times of risk.
00:08:00.34\00:08:04.25
I mean anything that
doubles the risk is significant.
00:08:04.26\00:08:06.90
And if it's a 50
percent increase risk,
00:08:06.91\00:08:08.69
which is 1.5 times
that's significant.
00:08:08.70\00:08:11.63
This was 7.69 times,
00:08:11.64\00:08:14.35
almost an eight fold
increase risk in stroke.
00:08:14.36\00:08:17.90
Just as a result of having
a high waist to hip ratio.
00:08:17.91\00:08:23.79
Now it turns out,
increased waist circumference
00:08:23.80\00:08:26.41
also showed a strong association
00:08:26.42\00:08:28.80
with the precursor of stroke
00:08:28.81\00:08:30.25
and that is TIA
00:08:30.26\00:08:31.53
or Transient Ischemic Attack.
00:08:31.54\00:08:34.06
And if your waist circumference
00:08:34.07\00:08:35.15
is greater than 40 inches
00:08:35.16\00:08:36.41
and you are a man watch out.
00:08:36.42\00:08:38.28
You dramatically
increase risk for stroke.
00:08:38.29\00:08:40.95
If it's greater than 34 inches
00:08:40.96\00:08:43.46
and you're a female
increased risk for stroke.
00:08:43.47\00:08:46.57
And so and of course
the less you are below that,
00:08:46.58\00:08:50.91
even the lower the risk
00:08:50.92\00:08:52.13
and so it's not just
trying to get it to 39 inches
00:08:52.14\00:08:55.22
if you're a man, but try
to get down there to the nice,
00:08:55.23\00:08:58.27
slim waistline and
the same for female
00:08:58.28\00:09:01.99
and you'll certainly
lower your risk of stroke.
00:09:02.00\00:09:04.12
So waist not what not,
00:09:04.13\00:09:05.43
or if you don't want a
stroke don't have a big waist.
00:09:05.44\00:09:08.19
So, where was that's study from?
00:09:08.20\00:09:09.17
That study was
from the journal Stroke,
00:09:09.18\00:09:11.29
published in July of 2008.
00:09:11.30\00:09:14.29
Okay, you know, we've looked,
00:09:14.30\00:09:15.27
you know, all the way from
sexual transmitted diseases
00:09:15.28\00:09:17.61
to, you know, whatever
it is more time outdoors
00:09:17.62\00:09:21.84
to what in without
a age in a healthy way
00:09:21.85\00:09:24.02
in our last
couple of minutes here.
00:09:24.03\00:09:26.01
Yes, and this was a study
00:09:26.02\00:09:27.29
from Great
Britain, United Kingdom.
00:09:27.30\00:09:29.74
Finding suggests that lifestyle
00:09:29.75\00:09:31.43
and other modifiable
factors can help counter
00:09:31.44\00:09:33.73
social disparities
in health and longevity.
00:09:33.74\00:09:36.63
This study came from 10,000
00:09:36.64\00:09:39.22
London Civil Service workers,
00:09:39.23\00:09:41.81
was the 17 years study.
00:09:41.82\00:09:44.00
They were 44
years of age on average
00:09:44.01\00:09:46.31
and they were free of
major diseases at the outset.
00:09:46.32\00:09:49.05
In fact, if they did
have a major disease,
00:09:49.06\00:09:51.42
they couldn't be
enrolled in the study.
00:09:51.43\00:09:53.85
And so with the 17 years study,
00:09:53.86\00:09:57.01
starting out at
age 44 and healthy,
00:09:57.02\00:09:59.19
they took to look
at several factors.
00:09:59.20\00:10:00.96
And 17 years later
00:10:02.19\00:10:03.84
they found only
13 percent of men
00:10:03.85\00:10:06.51
and 15 percent of women
00:10:06.52\00:10:08.49
were found to be
successfully aging.
00:10:08.50\00:10:11.00
That means that they
had no major illnesses
00:10:11.01\00:10:13.57
and they had good
physical and mental functioning.
00:10:13.58\00:10:16.57
So not too many people
are aged in a good way?
00:10:16.58\00:10:20.17
Yeah, and you know
that's before retirement even.
00:10:20.18\00:10:22.69
And so lot of people that are 44
00:10:22.70\00:10:24.28
and healthy they think,
00:10:24.29\00:10:25.26
hey this is the
way I'm gonna be,
00:10:25.27\00:10:26.38
they don't realize.
00:10:26.39\00:10:27.36
They have over
an 80 percent chance
00:10:27.37\00:10:30.18
that they are not
going to aged successfully
00:10:30.19\00:10:32.22
in the next 17 years.
00:10:32.23\00:10:34.50
And the odds of successful aging
00:10:34.51\00:10:36.71
depended to some degree
in their social position.
00:10:36.72\00:10:40.10
But they also found it
was independent of that,
00:10:40.11\00:10:43.58
particularly, if it was related
00:10:43.59\00:10:45.40
to lifestyle factors.
00:10:45.41\00:10:47.69
And the lifestyle factor
00:10:47.70\00:10:49.25
associated with healthy aging,
00:10:49.26\00:10:51.26
healthy diet, avoiding smoking,
00:10:51.27\00:10:53.64
getting regular physical
exercise and social support.
00:10:53.65\00:10:59.48
Those four factors were
related to successful aging
00:11:00.95\00:11:04.83
in a dramatically increased,
00:11:04.84\00:11:07.16
the likelihood
of successful aging.
00:11:07.17\00:11:09.59
So have some friends go
out and get on the move,
00:11:09.60\00:11:11.80
have so good food.
00:11:11.81\00:11:13.63
And probably one
of the strongest ones
00:11:13.64\00:11:15.42
again those are the friends.
00:11:15.43\00:11:17.09
Strongest ones as the friends
00:11:17.10\00:11:18.28
and also not smoking,
exercise and a healthy diet.
00:11:18.29\00:11:22.13
This was publish in
the Journal of the American
00:11:22.14\00:11:23.86
Geriatrics
Society, in June of 2008
00:11:23.87\00:11:27.43
and it was done
by Dr. Annie Britton.
00:11:27.44\00:11:32.03
Well, Dr Nedley these studies,
00:11:32.04\00:11:33.72
you know, all of them
that you have covered today
00:11:33.73\00:11:35.01
they are
fascinating and of course
00:11:35.02\00:11:37.63
have a lot of take home value
00:11:37.64\00:11:38.96
depending on where you are.
00:11:38.97\00:11:40.96
And no matter what
the situation you have,
00:11:40.97\00:11:43.25
you want to stop
it and prevent it
00:11:43.26\00:11:44.28
or avoid those different things.
00:11:44.29\00:11:46.04
Thanks for doing this research
00:11:46.05\00:11:47.12
